reoptimization is basically updating your sites with new techniques of optimization, updated keywords and content.
You all are mention that change in meta but any body explain me type of changes they are little bit or in high priority, I mean to say that we optimize our site............ they have new content OR META What is difference in RE-Optimization and Optimization Explain me with a example. Thanks
Re-optimization is to optimize a site for a new goal. For example; Let's say you are an accountant in New York and you have a website which is #1 in Google for "accountants in New York". That means your site is already optimized for your goal. Of course you will still have to put some continuous effort to keep your site in the rank 1. But this not re-optimization. Even struggling for a better rank is not re-optimization. But if you plan to move your office to Chicago, you will have to rebuild and re-optimize your site for "accountants in Chicago".
